6 Wire furnace & burner
Electric shock hazard. It can cause severe personal injury or death if power source, including the service switch on the
furnace, is not disconnected before installation or servicing.
Wire burner
The burner harness is factory-wired to the furnace. Plug the burner
harness into the matching burner connector. Refer to the wiring
diagrams on pages 15 and 16 for further information.
Install and wire thermostat
Locate the room thermostat on an interior wall in the natural
circulating path of room air. Do not locate thermostat so it is exposed
to cold air infiltration, drafts from windows or doors, air currents from
supply or return air registers, behind obstructions, on a shelf, in a
closet, or in a corner.
Ensure the thermostat won’t be exposed to heat from nearby
fireplace, radio, television, lamp or rays from the sun. Do not mount
thermostat on a wall over a supply or return duct, chimney or vent.
Wire thermostat to furnace and set thermostad anticipator as shown
on wiring diagram, pages 15 and 16.

Blocked Vent Shut-Off device wiring
(Optional)
1. Blocked Vent Shutt-Off device (BVSO)
2. Electrical kit supplied.
3. Connect one red wire to limit switch.
4. Disconnect red wire from limit switch and connect to one red
wire from BVSO.
5. Connect the green ground wire to a cabinet screw.
Connect power wiring
All wiring must conform to:
• National Electrical Code, ANSI/NFPA 70, latest edition and any
additional national, state or local codes.
• In Canada, CSA C22.1 Canadian Electrical Code Part One and
any local codes.
• Wiring must be N.E.C. Class 1. If original wire, as supplied with
furnace, must be replaced, type 105
o
C wire or equivalent must
be used. Supply wiring to furnace and additional control wiring
must be 14 gauge or heavier.
• Provide electrical ground at furnace as required by codes.
Connect 120 VAC/60 Hertz, single phase separate electrical line
from the main house panel to the power leads in the external
junction box as shown on wiring diagrams on pages 15 and 16.
Provide a fused disconnect in the power wiring, following all local
codes.
Ensure the wire size and type are adequate for the electrical load
(see Section 12 and furnace nameplate for value).
Limit control
The furnace is equipped with a fan switch/limit control. This control
limits the air leaving the heat exchanger to 200
o
F or less. The fan
switch continues fan operation until the air drops to a preset
temperature. For most installations, set the blower ON setting at
130
o
F and blower OFF setting at 90
o
F. If a longer cool down period
is desired, lower the OFF setting.
Counterflow furnaces also contain an automatic reset auxiliary limit
control to prevent blower motor and filters from being overheated.
